UPDATE: We’ve just added four more amazing titles to the Humble Indie Bundle 6! If you’ve already picked up a bundle, you’ll find BIT.TRIP RUNNER, Gratuitous Space Battles, Jamestown, and Wizorb available now if you beat the average. This brings the bundle to ten games strong!

Humble Indie Bundle 6 is upon us – and every single game makes its Ubuntu debut this time around. Humble Bundle veterans will know the drill by now, but if this is your first time, prepare to be amazed. For the next two weeks, you can pay what you want to for the following incredible new titles on Ubuntu:

It gets better. If your donation is higher than the average, you’ll be rewarded with a sixth game download: the frantic acrobatic platformer Dustforce! *Please note that the finishing touches for Vessel’s Ubuntu debut are still being completed and should be ready in 24-72 hours.

There’s something extra special about Rochard because it’s the first native game based on the Unity engine to make it into both the Humble Bundle and the Ubuntu Software Center. The team at Unity is dedicated to their mission to democratize gaming, while strengthening their cross-platform gaming platform with the ability to export to Ubuntu.

With the Unity 4.0 release later this year, we can expect a raft of new games on Ubuntu. So it gives us great pleasure to welcome all Unity developers to what is easily the most enthusiastic indie gaming community.

To make life easier for independent game developers, we’ve been working hard to streamline the process of bringing new games to Ubuntu. Canonical has been developing a new service as part of our developer program to automatically package your applications – and that includes Unity games. This means developers can focus on their software, while Canonical takes care of the packaging for Ubuntu.

To learn even more about the games, check out the Humble Bundle site, where you’ll also find information about soundtracks, redemption through both the Ubuntu Software Center and Steam and donations to this bundle’s chosen charities: Child’s Play and the Electronic Frontier Foundation.

You have two weeks from now to get six brand new games for whatever price you think they’re worth. So lets make this bundle even bigger than the last one for Ubuntu – and the coming wave of gaming titles that continue to make Ubuntu great.
